NEW JERSEY.

T his invention relates to shoe sewing machines and more particularly toa wo-nk supin shoe sewing machines of thewelll'cnown McKay vpe. the worksupported during the operations. upon a horn ended withinthe shoe,I'leretofore, such work supporting l-i-or-ns have been provided .with aguard between 'Wl'Ll'C'l] and the'body of the hofrnthe thread pa-see tothe usual whirl located in thin? tip .o;'t the horns Such guards havebecninadcof a sin lepiece of metal and serve the pu )ose of protectingthe lining ofthe shoe in (the wax thread as the latter is drawn throuthe whirl during the sewing operation. In the event of thread breakageconsiderable inconvenience and delay has been heretofore encountered inreaching the broken end of a thread between the guard and the bodyportion in order to re-t-hrea-d the whirl, and usually in such instancesthe usual "practice has been to pry open the tip of the guard with ascrew driver or other implement. This procedure resulted oftentimes inbreaking off the tip of the guard, thereafter exposing the shoe liningto the wax thread.

The object of the present invention is to provide an improved horn forsewing machines in which in the event of thread breakage, ready accessmay be had to the end of the thread between the horn guard and the bodyportion of the horn, so that the whirl may be readily re-threaded. thuseliminating the breakage of the tips of the horn guards. h To this endthe invention consists int-he work supporting horn for sewing machineshereinafter described and claimed.

In the accompanying drawings illustrating the preferred embodiment ofthe invention Fig. 1 is a vertical sect-ion of the im- I proved horn;and Fig. 2 is a front elevation of the horn guard.

The improved horn illustrated in the drawing comprises the usualupwardlycurrcd body portion .1 which is, secured to the usual basenotshow in position to enter the shoe and support it during the saw ingoperation. The body portion 1 is provided with a whirl 4 in theupper'end portion thereof of the usual construction, driven from the camshaft of the sewing machine in the usual manner through a norm FDR snwmeMACHINES.

; The body portion1of the horn is pro .vided with a guard 20 forprotecting the lining of theshoe from. the wax thread as the latterpasses upwardly between the guardaruil the body portion 1 of the horn onits ay to the .whi-rl 4;. In ,order to aiford ready access to the threadbetween the guard and body portion so that in event of thread breakage"theopcrator-may quickly and conveniently ireachthe end oft-he brokenthread to re-thri-zad the whirl, provisionis made for permit-tinga.portion of the guardto ,be swung o-utvviardly from the body 3 ,portion;of the guard. For this purpose the guard 20 ism-ade 'inntwo parts, alower part 24 rigidly secured to the body portion 1 by screws 26 andanupper or tip portion 28 pivoted upon the upper end of the lower orstationary portion 2 1. The tip or upper portion 28 of the guard isprovided with a tongue 29 which fits into a corresponding groove 31 inthe lower or stationary portion 28 of the guard, as shown in Fig. 2. Apivotal pin 33 extends through the tongue 29 so that the tip or upperportion 28 of the guard is capable of pivotal movement outwardly aboutthe pin '33 as a center. A spring 35 secured by screws 36 to the face ofthe lower or stationary portion 24 of the guard, bears against the upperor tip portion 28 thereof to yieldingly hold the latter in an operativeposition, as shown in Fig. 1, and to permit the tip or upperportion ofthe guard to be conveniently and easily swung outwardly.

The thread as it comes from the usual wax pot, not shown, passes betweenthe guard 20 and the body portion 1 of the horn, entering through an eye40 formed in a support 42 secured by screws 44 to the under face of theguard, as shown in F 1. The thread is led around a guide pulley 46journaled in the support 42and thence over a second guide pulley 48journaled in the upper end of the stationary portion of the guard andthence under the tip of the guard to the whirl 4:. I

From the foregoing description of the construction of the improved hornit will he breaks access is afforded to the broken end apparent that inthe event that the thread restored to operation, in the event of threadbreakage, with a minimum delay.

' While' the preferred, fornr the inven' tion contemplates the pivotaland yielding mounting of the upper or tip portion of the c guard, it isto be understood that viewed in its broader aspects the inventioncontemplates any construction of horn in which one portion of the hornguard may be swung outwardly to afford the desired access to the end ofa broken thread.

Having thus described the invention what is claimed is:

1. A work supporting horn for sewing machines of theMcKay type having abody portion provided with a whirl, and a horn guard removably securedto the horn extending longitudinally of the horn between which and thebody portion of the horn the thread passes to the whirl, the horn guardhaving 30 provision whereby the tip portion thereof may be swungoutwardly with relation to the rest of the guard to afford ready accessto the end of a broken thread thereunder.

2. A work supporting horn for sewingmachines of the McKay type having,in combination, a body portion provided with a whirl, and a horn guardremovably secured to the horn extending longitudinally of the hornbetween which and the body portion of the horn thethread passes to theWhirl,'t-he upperportion of the horn guard being pivoted to the lowerportion of the guard to enable it to be swung outwardly to afford accessto the end of a broken thread thereunder. I

3.1x work supporting horn for sewing machines of the McKay type having abody portion provided with a whirl, a horn guard extendinglongitudinally of the horn under which the thread passes to the whirl,comprising a lower portion removably secured to the body portionof thehorn, an upper portion pivoted to the lower portion, and a spring foryieldingly maintaining the upper portion in an operative position andfor permitting the upper portion to be swung outwardly to afford accessto a broken thread thereunder. r
